Swartzia thomasii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Swartzia thomasii faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Atlantic Forest of Brazil. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and urban development further reduce available habitat, while the slow growth rate typical of leguminous trees limits the species' ability to recover from disturbance.
Habitat
Swartzia thomasii is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, occurring in lowland and montane rainforest environments. The species typically grows in primary forest understory and forest edges, preferring well-drained soils in areas with high humidity and consistent rainfall.
